In terms of graphics quality compared to PC. Same. I am running a AMD Radeon HD 7900 single card (which is old now) and no difference in quality of the game during normal play. However when you go into CT for example and start fighting KB, the PC is far more smoother. The screen is choppy on the PS4. It cant seem to handle too much going on. And before you ask, its not lag from the internet. Had 2 accounts logged into same fight. PC was fine, PS4 choppy. My bandwidth is 50MB Down and 15MB up just in case your thinking that.

So problems so far with PS4 compared to PC:
1. Lag in keyboard response
2. Choppy graphics when in battles with large number of players in area.
3. Slower Load Times compared to PC (Probably HDD in PS4 versus SSD in PC)

Good thing about PS4 is its smaller than the PC and generates far less heat so far. But it does crank up the fan which is loud but the TV sound overpowers that.

Will keep playing to see what else there is.
